We study the fixed point for a non-linear transformation in the set of Hausdorffmoment sequences, defined by the formula: T ((an))n = 1/(a0+�E �E �E+an).We determine the corresponding measure�E, which has an increasing and convex density on ]0, 1[, and we study some analytic functions related to it. TheMellin transform F of �E extends to ameromorphic function in the whole complex plane. It can be characterized in analogy with the Gamma function as the unique log-convex function on ].1…

On a fixed point in the metric space of normalized Hausdorff moment sequences
We show that the transformation (x_n)_{n\ge 1}\to (1/(1+x_1+...+x_n))_{n\ge 1} of the compact set of sequences (x_n)_{n\ge 1} of numbers from the unit interval [0,1] has a unique fixed point, which
On an Iteration Leading to a q-Analogue of the Digamma Function
We show that the q-Digamma function ψq for 0<q<1 appears in an iteration studied by Berg and Durán. This is connected with the determination of the probability measure νq on the unit interval with
On Markov Moment Problem and Related Results
New results and theorems on the vector-valued Markov moment problem are proved by means of polynomial approximation on unbounded subsets, also applying an extension of the positive linear operators’ result.
From Hahn–Banach Type Theorems to the Markov Moment Problem, Sandwich Theorems and Further Applications
The aim of this review paper is to recall known solutions for two Markov moment problems, which can be formulated as Hahn–Banach extension theorems, in order to emphasize their relationship with the
On Markov Moment Problem and Mazur-Orlicz Theorem
Applications of the generalization of Mazur-Orlicz theorem to concrete spaces are proved. Suitable moment problems are solved, as applications of extension theorems of linear operators with a convex

Moment problems and orthogonal polynomials
In 1894 Thomas Jan Stieltjes (1856-1894) published an extremely influential paper: Recherches sur les fractions continues, Ann. Fac. Sci. Toulouse, 8, 1–122; 9, 5–47. He introduced what is now known
Moment Problems on Bounded and Unbounded Domains
Using approximation results, we characterize the existence of the solution for a two-dimensional moment problem in the first quadrant, in terms of quadratic forms, similar to the one-dimensional
On the Moment Problem and Related Problems
Firstly, we recall the classical moment problem and some basic results related to it. By its formulation, this is an inverse problem: being given a sequence (yj)j∈ℕn  of real numbers and a closed

The Markov moment problem and de Finetti’s theorem: Part I
Abstract.The Markov moment problem is to characterize sequences admitting the representation sn=∫01xnf(x)dx, where f(x) is a probability density on [0,1] and 0≤f(x)≤c for almost all x. There are
Some Transformations of Hausdorff Moment Sequences and Harmonic Numbers
Abstract We introduce some non-linear transformations from the set of Hausdorff moment sequences into itself; among them is the one defined by the formula: $T\left( {{\left( {{a}_{n}} \right)}_{n}}
On Powers of Stieltjes Moment Sequences, I
For a Bernstein function f the sequence sn=f(1)·...· f(n) is a Stieltjes moment sequence with the property that all powers snc,c>0 are again Stieltjes moment sequences. We prove that $$s_n^c$$ is

Regular Variation in R k
Researchers investigating certain limit theorems in probability have discovered a multivariable analogue to Karamata's theory of regularly varying functions. The method uses elements of real analysis
